Bare Skies - Trailers' sky

Changes:

Fixed stars in the night sky. Previously, most stars made of 2, 3 and 4 pixels did not have a square shape.

The Pale Garden night sky now has its own texture, with the same star pattern as the night sky for the rest of the biomes, but with a black background.

Finally, transition values ​​for the dark blue evening sky have been adjusted to better blend with the night sky.
